+NumPy is a general-purpose array-processing package designed to
+efficiently manipulate large multi-dimensional arrays of arbitrary
+records without sacrificing too much speed for small multi-dimensional
+arrays.  NumPy is built on the Numeric code base and adds features
+introduced by numarray as well as an extended C-API and the ability to
+create arrays of arbitrary type which also makes NumPy suitable for
+interfacing with general-purpose data-base applications.
+
+There are also basic facilities for discrete fourier transform, basic
+linear algebra and random number generation.
+
+If you need to build numpy for debugging, set DEBUG=y. If you use software
+which is having problems with numpy's new relaxed strides checking, set
+NPY_RSC=0.
+
+It is highly recommended to install libraries implementing BLAS and LAPACK
+before installing numpy. You may choose between:
+   a) BLAS and LAPACK (reference but unoptimized and thus slow)
+   b) OpenBLAS (optimized, provides LAPACK too)
+   c) ATLAS and LAPACK (optimized), good to read README.ATLAS
+All these are available on SlackBuilds.org.
+
+If you want to use the UMFPACK library instead of SuperLU to solve unsymmetric
+sparse linear systems, then run this Slackbuild with NO_UMFPACK set to "no"
+and then install scikit-umfpack on top of scipy. In this context, UMFPACK is an
+optional dependency for numpy. Nevertheless, note that presently scikit-umfpack
+is not available on SlackBuilds.org while its dependencies are.
+
+NOTE: If you use this SlackBuild numpy will run with the python 3 version
+      installed on your system. If you'd like to use python 2.7.xx as
+      provided by Slackware Linux then you have to install it with the
+      numpy-legacy SlackBuild.
+
+IMPORTANT: This version, 1.8.2, is the latest to include the oldnumeric
+           and numarray compatibility modules. Starting with version
+           1.9.0 these modules got removed by the numpy developers.
+           THUS: This SlackBuild conflicts with the numpy3 SlackBuild
+                 which installs versions >= 1.9.0!
